The issues of climate change and security of energy supply are complex and closely intertwined. Unless renewable energy moves quickly to the top of every government’s agenda, our ability to significantly reduce the harmful levels of carbon dioxide in the atmosphere look increasingly unlikely. But what happens if we are unable to reduce our global carbon emissions? Geoengineering, the deliberate, large-scale intervention in the Earth’s natural systems to address climate change, provides one possibility of a solution. But are we willing to risk the implementation of such drastic measures and if we are, what assurances do we have that it will do more good than harm?
